Description

When I write a no-effect statement such as 1 2, Solidity compiler warns me that it has no effect. But when I substitute 1 with x, no warning is issued. Does "x 2" have any side effect, such as changing the value of x or increase the memory cost?

Environment

  • Compiler version: 0.8.27-develop.2024.6.25 commit.ce4be6e1.Darwin.appleclang
  • Operating system: Macos M2 Sonoma 14.5
